Specification of Letters Patent.

Patented Oct. 13, 1921.

Application filed June 9, 1919, Serial 110 302342. Renewed August 27, 1921. Serial No. 496,164.

particularly to that type shown in my application Serial No.'242,445, filed June 28, 1918.

In my co-pending application above identified, use is'made of a heavy rotor having an interior annular clutch surface and a revolving hanger carrying clutch devices adapted to be canted and brought into active clutch engagement with said interior annular surface so that motion imparted to the duced. In the improvements which will be presently described in detail, I have provided an arrangement somewhat similar to the one described above but functionally operable to create a more positive clutching contact between the respective clutch elements and thus insure quicker action of the rotor against the diaphragm and in fact synchronize the action of the rotor with that of the power transmitting mechanism and thereby cause sound to be immediately created through vibrations of the diaphragm.

lessen the cost of manufacture of the device while designing such parts for the purpose of establishing quick and positive action and one which will work with minimum resistance.

The various important features will be particularly pointed out hereinafter in connection with a detailed description of a preferred embodiment of my invention which I have selected for illustration in the accomtor and its hollow support.

' through the device with parts broken away and parts in section. Fig. 2. is an enlarged view of the rotor showing the movable clutch devices in active clutching positions in full line and in inactive positions in dotted lines.

Fig. 3 is a vertical section through the ro- Fig. 4 is a vertical transverse section taken substantially on the line 4i-4 of Fig. 3 and,

Fig. 5 is a vertical section taken substantially on the line 5-5 of Fig. 3. Y

In carrying the invention into practice use is preferably made of a case 6 having a resonator 7 and at the juncture of the latter with one end of the case is a diaphragm or I vibratory member 8 of usual well know conhanger will be transferred to the rotor when struction and provided with a wear piece or anvil 9.,

Within the case and secured thereto by screws or the like 10 is a plate 11 having a plunger guide 12 and parallel bracket extensions 1313. Mounted in said extensions 13-13 is a stationary axle 1 1 on which is loosely mounted a revoluble support 15.

The support 15 is provided with a gear surface 16 and at one side of said surface is a reduced cylindrical extension 17 and on said extension is loosely mounted a heavy rotor 18 having an external anvil striking surface 19 and an internal clutch surface 20. At the side of the cylindrical extension and formed as a part of the mentioned support 15 is an extension 21 having key or flat faces 22-22. This last named extension projects through a corresponding opening 23 in a disk like bodyor hanger 241 It will be oh- I have also simplified the construction andarrangement of parts so as to materially served from this construction that said body or hanger is adapted to rotate with the support 15. In the body or hanger at diametrical opposite positions are recesses 24 having relatively diverging walls 25 and 26 conne'cted by an inner curved wall 27. In the recesses are mounted rigid clutch devices 28 which may be formed of metal, fiber or the like and as shown the width of each of these devices is less than that of the recess in which it is mounted so that it can freely rock or oscillate in said recess. The width of each of these devices increases in the direction of the clutch surface 20 of the rotor 18 and at the outer end said devices are provided with arcuate surfaces 29 adapted when the devices are in clutching positions to uni- -the plunger 3 1'. On the return movement formly engage with said surface 20 and 15 meshes with a gear wheel 30 on a driven shaft 31, the latter carrying a pinion-.-32, whichmeshes with the rack surface 33 o f a sliding plunger 34:. The plunger is yield ingly held in a starting orelevated position bymeansof a spring 35, one. end of which is seated against one end of the plunger and the other end against the adjacent wall-of the case 6. The plungebisrecessed atone 2 side as at 85,-"the base. wall. ofawhich constituting a stopwhich co-acts witha lug 36 carried by the platell; This. arrangement serves to prevent casual separation of the plunger from the. mating. pinion 32.

Having described the essential features of construction, ofthe. device its. operation p without depart ng-froniimy invent on;

is as follows:

When the plunger is presseddownwardagainst the actionof-the spring 35, power therefrom will be transferred to the, pinion 32 and thence to the revolving. support 15 in fiat contact with the walls 2610f: the r.e--

cesses 24:. Under this action the rotor becomes fixed to the revolving support 15 and both are moved together on actuations of of theplunger, the active force thereof having been spent, the relative positions of the clutch devices 28 and the surface 20 autoof said recesses 24 so that the surfaces 29 of said devices are free with respect to the mentioned annular surface 20. This cycle.

ciated, when used in connection with a heavy rotor of the design described and by using clutch devices of long and rigid construction and causing the same to co-act with the remote surface 20 or a surface at or near the periphery of the rotor, high power will be quickly created in the rotor to instantly disturb the diaphragm and produce sound. of high intensity and amplitude, the freeing of the rotorfrom the driving mechanism permitting the rotor to spend its entire en-'.

ergy against the diaphragm.

In order to permit. of free rocking motionof the clutch device 28, the inner ends thereof are curved to correspond with the walls .27 of the recesses 24:- The walls 25 and 26 of saidrecess serve also to encourage movements of the devices 28, to active clutching positions. [IVhen said devices 28 are in the dotted line positions shown in Fig.2, it will be observed that only small portionsof the surfaces 29 contact with the surface 20 so as to reduce friction between such parts. A
